COMBINATION COMPASSES AND MARKING-GAGE.

To all whom it may concern Be it known that I, NELSON L. KUNKEL, a citizen of the United States, residing at Utica, in the county of Oneida and State of New York, have invented a new and useful Combination Compasses and Marking-Gage; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a pair of calipers or compass, utilized particularly in combina tion with a two or three foot rule, whereby, by the employment of said rule, the pair of calipers may be partly converted or transposed into an improved form of carpenters marking gage, as particularly illustrated in Figure 1 of the drawings.

To accomplish the above object of the invention, the compass or pair of calipers is provided with a flat bar adapted to slide against the edge of a board, and provided with means whereby a rule may be clamped between the legs of the calipers, in order to extend out beyond said bar, whereby a pencil or the like may be arranged adjacent thereto, thereby enabling a carpenter or other mechanic to gage and mark a piece or strip of lumber.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings :Fig. 1 is a perspective view showing a rule carried by a pair of calipers, thereby transposing or converting said calipers into an improved mechanics marking gage. Fig. 2 is a View showing the calipers and rule combined or held relative to one another in order to be placed in the mechanics pocket. Fig. 3 is a view of the calipers used for scribing a circle.

Referring more particularly to the drawings, 1 and 2 designate the legs of the calipers. Said legs are pivotally connected as at 3. The leg 1 is provided with an elongated slot 4, while the leg 2 is constructed with a slot 5, but slightly shorter than the slot 4. By making the slot 4 longer than the slot 5, it renders it easier to insert the threaded shank 10 through the opening 1. The leg 1 is constructed with an integral extension 6, which integrally connects to a bar 7, which is located beyond the pivot 3, and trans- Specification of Letters Patent.

versely thereof. A segment bar 8 pivotally connects at 9 to the bar 7. The segment bar is curved on the arc of a circle using the pivot 8 as a center. This segment bar 8 eX- tends through a slot 5, and terminates in a cylindrical threaded shank 10. This threaded shank 10 passes through the slot- 4, and has threaded thereto a thumb nut 11, the purpose of which will hereinafter appear. A thumb screw 12 extends transversely of the leg 2 from one face thereof, and engages the segmental bar 8, in order to hold the legs of the calipers in adjusted positions. Upon one face of each log are lugs 18. Between these lugs 13, a rule 14: may be clamped, as shown in Fig. 1. The lugs 13, which are triangular, in cross section, are inclined toward one another to partially overlie the rule, in order to prevent outward displacement of the same, when clamped between the lugs. By placing said rule between said lugs and holding the legs together, until the thumb screw 12 is thoroughly tightened, the rule may be held firmly clamped in position, with one end of the rule extending beyond the bar 7. Then by placing the bar 7 against a piece of lumber with a pencil or the like placed adjacent the outer end of the rule, as shown in Fig. 1, a mechanic or carpenter may, by moving the bar along the edge of the timber, mark the piece of lumber or timber as desired. After tightening the thumb screw 12, the rule may be further clamped, or rather the legs may be held firmer in position, by tightening up the thumb nut 11.

The invention having been set forth, what is claimed as new and useful is t- 1. In combination with a rule, a pair of calipers comprising a pair of legs pivotally connected and provided with opposing lugs between which said rule is arranged, and connections between said legs including means whereby the legs are held in such positions as to clamp the lugs against the rule, said connections including a bar adapted to slide against a strip of lumber, and said rule extending transversely over said bar, whereby said strip of lumber may be marked.

2. In combination with a rule, a pair of calipers comprising a pair of legs pivotally connected and provided with opposing lugs, between which said rule is adapted to be clamped, said calipers having a bar adapted to slide against the edge of a piece of lumname to this specification in the presence of her, and said rule extending transversely two subscribing Witnesses. over said bar, whereby a pencil may be dis posed adjacent the extreme end of the rule NELSON KUNKEL' 5 in order that a desired portion of the lumber \Vitnesses:

may be gagged and then marked. ERMA KUNKEL,

In testimony whereof I have signed my GEORGE H. KUNKEL.
